It looks like I was actually using the 0.9.3 version of libapt-pkg4.12
(due to some previous debugging efforts) even though I had 0.9.6
installed. Once I fixed that, rred quit segfaulting.

Are you sure about the version numbers involved?

The backtrace doesn't match with the code as FileFd::Close doesn't have
a gzclose() call itself anymore, but offloads it to FileFdPrivate::CloseDown.
This looks more like 0.9.3 which really had a gzclose call at line 1675.

Bug#677330: rred crashes in apt-get update

[Courtney Bane]

Package: apt
Version: 0.9.6
Followup-For: Bug #677330

I'm not positive that this is the exact same problem, but I'm still
seeing segfaults in rred with apt 0.9.6. I rebuilt rred with debugging
information before my latest crash, and was able to get a full
backtrace. I've attached a file with the short and full backtraces. I've
also saved the core file, the actual rred executable used, and the
contents of my /var/lib/apt/lists from before running "aptitude update";
I've put a tarball of these up here:
.

Here's the short backtrace:

Are you sure you experience these crashes with this version?
(And is it really this version given that your distribution is reported
 as being ubuntu which has a different version scheme)

This bug is supposed to be fixed in 0.9.5…
(#554387 and his various "friends")

Bug#677330: rred crashes in apt-get update

[Steffen Moeller]

Package: apt
Version: 0.9.5.1
Severity: normal

Hello, I see segfaults during apt-get updates, reproducibly. A second 
invocation then always works fine. This is what I see, but this does not tell 
too much:

Core was generated by `/usr/lib/apt/methods/rred'.
Program terminated with signal 11, Segmentation fault.

There is no -dbg package for apt as it seems. Please consider adding such.

Thanks
